Sewer Tie-Ins & Underground in Portola, Plumas County

BC Brown General Engineering has handled sewer work across Portola and Plumas County since 1999. Portola is a high-elevation railroad town in Sierra Valley along the Middle Fork Feather River, where winters are long and cold, and that local knowledge shapes how we approach every job here.

In Portola we bury lines below frost depth, trench through rock where the mountain insists, and backfill to a standard that handles freeze-thaw.

Most of Portola is beyond a sewer main, so the underground work is private, laterals, tank lines, and drainage. Where a connection does exist, we trench, set proper fall, and tie in cleanly; where it does not, we handle the on-site lines.

Portola is east over the mountains into Sierra Valley, so we mobilize crews and equipment there regularly and keep our response times short. We coordinate the tie-in and inspection with the local sewer authority and pull any permits the connection requires.
